Except for the details of construction and operation of the ejectingmechanism, the heel-press 10 is like that disclosed in applicantsLetters Patent of the United States No. 1,452,671, dated April 24, 1923,and assigned to the United Shoe Machinery Corporation, and thereforeonly a brief and general description of the common features of themachine will be given, reference being had to said patent for a moredetailed description, if desired.

The heel-press 10 comprises an annular rotary carrier 20 which turns ina horizontal plane and supports a series of unit heelclamps 22 havingrelatively movable, upper and low-er, substantially horizontal, heelengaging members or jaws 24, the parts being so arranged that heelsmaybe introduced to and from the clamps by movements in a horizontalplane. The rotary carrier 20 is moved intermittently, in the samedirection, to bring the clamps 22 successively to a station 26 where theclamps are opened and the heels discharged therefrom. After thedischarge of the heel from a clamp at the station 26, a fresh heel isloaded into the open clamp which closes upon the heel before the carrierstarts its next feed movement. The intermittent feed movement of thecarrier is effected by a suitable can] on a cam-sleeve 28, the sleevebeing intermittently rotated by clutch mechanism 30 that is driven froma continuously operated power shaft 32. By means of the clutch mechanism'30 the press is caused to perform a single cycle of operations afterwhich it is automatically arrested until again thrown into operationunder the control of the operator.

The loading of the press is affected by a manually controlledspring-actuated feedarm 34 (Fig. 3) which is adapted to swinghorizontally across a feed-table 35 toward and from the loading anddischarging station 2-6. The operator places a. previously pasted roughheel, which is to be loaded into the press, between a pair ofgage-members 36 that are carried by the feed-arm. The feed-arm isnormally positioned and latched at one side ofthe feed-table 35, asshown in Figs. 1 and 3, and when a heelis placed between thegage-members 36 the heel is temporarily supported by a tripplate 38which controls the operation of the feed-arm. By exerting a slightdownward pressure on the heel, after it has been placed between thegage-members 36, the operator causes the trip-plate to be depressed,whereupon the feed-arm is released and swings inwardly, carrying theheel into an empty clamp at the station 26, the movement of the heelbeing limited by a breast gage 40.

As so far described, the operation of the parts is the same as describedin said Patent No. 1,452,671., above referred to. In the machine of saidPatent, however,the breastgage operates, just prior to the loading of aheel into a clamp of the rotary carrier, to eject from the clamp theheel which had been previously inserted therein and which has been heldthereby a sufficient time for t e setting or drying of the paste. In thepresent machine, however, inasmuch as the transferrer 16 is provided forremoving the heels from the clamps 22, it is not necessary a for thebreast-gage 40 to perform also the function of an ejector. Accordingly,while the same provision is made, in the present as in the priormachine, for retracting the breast-gage 40, prior to each rotation ofthe clamp-carrier, the breast-gage is thereafter moved slowly toward theclamp, advancing slightly beyond normal position to dislodge the heel,in case it should be stuck in the clamp, and immediately being returnedto its normal breast gaging position.

The compressor 12 (Figs. 1 and 2) is of a wellknown type and, with theexception of its driving mechanism and its starting and stoppingmechanism, is similar in its general characteristics to the machinedisclosed in United States Letters Patent No. 1,213,052, granted January16, 1917, to the present applicant, and assigned to the United ShoeMachinery Corporation. The con-' struction and operation of thecompressor need not therefore be described in detail. It should beunderstood, however, that the compressor is provided with the usualheelcompressing instrumentalities comprising a stationary heel-seat die,which is not shown in the drawings, but which is supported on the upperportion of a frame 42, and the usual heel mold (not-shown) which iscarried by a vertically reciprocating cross-head 44, and is adapted tocooperate with the die to compress and shape a heel. Secured to thecross-head 44 and reciprocated therewith is a feed-table 46 whichv isprovided with the; usual side-guides 48 upon which the usual feed-slide50 reciprocates horizontally for the purpose of feeding heels intoposition to be operated upon.

The mechanism for driving the compressor is similar to that disclosed inUnited States Letters Patent, No. 7 7 6,87 5, granted December 6, 1904,to E. A. Tripp, and assigned to the United Shoe Machinery Corporation.As therein illustrated and described, the compressor is adapted to bedriven from a driving shaft 52 (Fig. 1) which is mounted in bearings inthe rear portion of the supporting frame and is provided with fast andloose pulleys 54 and 56 respectively.

Thedriving shafti 52 is connected through suitable gearing with acrankshaft 58 anda link 60 operativelyconnects the crank-shaft with anoperating "toggle (not shown) -by means of which the cross-head 44 isiecip rocated.

'The' startingand stopping of the com-' press or is effected by'shifting-a, drivingjbelt into or out of en 'agementlwith the fast pulley. 54.The means fer shifting the drivingbelt, as also shown in the abovementioned Tripp patent, comprisesja belt-shifter 62 which slides in abearing 64 at the rear of the frame 42 ot the CGHfllJIGSSO-l'l The 1shaft 68 and acted uponby a suitable spring 72 which tends to raise thearm and main tain the driving belt in engagement with the loosepulley/-52. Provision is also made for automatically depressing andraising the arm 70 to control t-hefstarting and stopping of thecompressor.

The means for thus automatically controlling the starting and stoppingof the compressor constitutes a. feature otthe present invention andcomprises a lever 74: (Figs; 6 and 0) which is fulcrumed at one end on astud 76 carried by the compressor frame 42. Atits opposite end the lever74; is provided with a spring pressed plunger 7? which bears against theupper longitudinal edge of the arm 70. The lever Tel is adapted to beactuated by means of a togglecomprising members 78 and 80. The togglemember-78 is'pivotedat 82 the lever 74 and the toggz le member ispivoted on a stud 84 carried by a bracket t-hat is secured tothecompressor frame 42. The two toggle meml'lers are connectedtogether bymeans a knucl zle pivot stud 86.

lnorder that the toggle 7880 may beopera-ted periodically by theheel-press, the knucl zle pivot-stud 86 is connected by means of a rod88 with one arm of a cam lever 00 (Fig. 8) which is l'u lcrumed in abracket 92 p-roiect inp from the trams or the press. The other arm ofthe :cam lever carries a cam roll .9 1 which rides againstthe innerlateral face of :a cam 06 which issec ured to the ca-n'i-sleeve 28 ctthepres-s l0.

Shortly after the press 10 has started its cycle-oil operations. the.turningof'the cam 96 causes the 78S0 to be straightened "and-the lever-4!; to be swung downwardly. As the lever Yet-and theplunger 77. movedownwardly, [the arm 7 0 isdepressed, thus rocking the shait '68 andthrowing thebeltshifter 62 to start the compressor. The shifting of thedriving belt is completed just before the toggle becomes fullystraightened and thereafter the spring pressed plunge-r Y7 yieldsupwardly to permit thea'dditi'onal downward movement of the lever "'54caused by the swinging of the knuckle pivot 86 to dead center. The cam96causes' the knuckle pivot of the toggle tobe carried just beyond deadcenter, whereupon the edge of the toggle linl: TB'engages a'flatface98011 the'lever 7 which prevents further lDOVBHlQDlZj toward the left inFig. 6 or said pivot, so that the arm 70 is held depressedand thedriving belt is maintained in driving engagementwith the fast pulley ofthe compressor; V

The conveyer' 14c meansof which [the heels arecarried from the press tothe compressor, comprises an endlesschain such, for example, as thatshown in the applicants Pa'tentNo-J 1,213,052, hereinbeitore mentionedThe conveyer chain extends from the press tothe compressor and issupported by two sprocket wheels 100 "and 102, each consisting of apairof notched diskswh'ich are fixed side-by-side on a common axle. Theaxle of the sprocket wheel 100 (Figs. 3 and 4) is journaled in a bearingbracket 103 that is secured to thejtrame of the press and the axle ofthe sprocket wheel 102 2 and 7) is journaledxin suitable bearingssupported by the frame 1-2 of the compressor.

Theconveyer chain,as describedin, the

aforesaid patent, comprises a series of flat links 10lwhich are pivotedtogether endto-end by transverse pivot rods 105, the pivot rodsextending through lateral flanges 106' which projectv downwardly fromthe links." Each linlrlOd is provided with a transverse rib 108 whichengages the breast edge of" the heel. At each side of the conveyer chainthe pivot rods are provided withrollers 110 which are received in thenotches in the sprocket wheels.

In the present machine it is desirable that thelink-otf the conveyerchain which is in position to receive a heel from the transferrer 16 andthe link from which a heel is tobe removed by the transterrer 18 shallbe supported in a horizontal plane. Inasmuch as the delivery end of theconveyer which 1s the sprocket wheel 100 and asthey approach thesprocket wheel i102. To this end a pair of guide members 112 (Figs '1, 3and 1) are secured to the bearing bracketdOS, and a pair of guidemembers 11 1 l and 2 are-securedto a portion'o'f the frame 42 of thecompressor,. and these members are adapted to engage the rollers 110 soasto maintain the links in the conveyer chain horizontal while they areadjacent the guide members.

The conveyer 14 is actuated step-by-step, be feed mechanism which isassociated with the compressor and derives its power from thereciprocations of the cross-head 44 and feed-table 46. This feedmechanism, which is a feature of the present invention, acts during theoperation of the compressor, while the cross-head 44is rising, toadvance the conveyer chain through the space of one link.

As shown in Figs. 2 and 7, the mechanism for advancing the conveyer 14comprises a ratchet wheel 116 which is secured to the axle of thesprocket wheel 102, and which is adapted to be rotated by a. feedingpawl 118. The pawl 118 is carried by an arm 120 which is pivotallymounted on the axle of the sprocket wheel 102, and a suitable spring isprovided for holding the pawl against the ratchet wheel; In order thatthe pawlcarrying arm 120 may be oscillated to efiect the feeding of theconveyer chain, said arm is connected by a link 122 with the bent upperarm of a lever 124 that is pivota'lly mounted on a bracket 126 on theframe of the compressor. The lower arm of the lever 124 carries a roll128 which is received in a cam slot 130 that is formed in a plate 132depending from the feed-table 46.

Upon the upward movement of the crosshead 44 and feed-table 46, one sideof the cam slot 130 causes the lever 124 to be rocked so that the feedpawl 118 will rotate the ratchet wheel 116 through the space of onetooth and advance the conveyer chain through the space of one link. Uponthe descent of the feed-table 46 the opposite side of the cam slot 130causes the lever 124 to be rocked in the opposite direction so that thefeed pawl 118 is retracted idly over one toot-h of the ratchet wheelpreparatory to its next feed movement.

In order to insure against accidental advancement of the conveyer duringits periods of rest provision is made for locking the conveyer chainafter each feed movement thereof. To this end a second ratchet wheel 134is secured to the axle of the sprocket wheel 102 alongside of theratchet wheel 116, the teeth of the ratchet wheel 134 being pitchedoppositely to those of the ratchet wheel 116. The ratchet wheel 134 isengaged by a. locking pawl 136 which is pivoted on a fixed stud 138 andis normally held in looking position by a spring 140, one end of thespring being secured to a fixed part of the frame and its opposite endbeing secured to a tail 142 on the locking pawl.

It is necessary to disengage the locking pawl from the ratchet wheel 134prior to each feed movement of the feeding pawl 118 to permit theadvance of the conveyer chain, To this end the tall 142 of the lockingpawl is engaged by the upper end of a trip-bar 144 having its lower endpivoted to one arm of a bell-crank lever 146 that is pivoted at 148 tothe bracket 126. The other arm of the bell-crank lever 146 carries aroll 150 which is received in a cam slot 152 in the plate 132 of thefeed-table 46. The trip-bar 144 is normally maintained in operativeengagement with the tail of the locking pawl by a spring 154, one end ofwhich is secured to the trip-bar while its opposite end is secured to abracket 156 on the frame of the compressor.

As the feed-table of the compressor rises, the trip-bar 144 is elevatedsufliciently to disengage the locking pawl 136 from the ratchet wheel134. Continued upward movement of the trip-bar 144 causes a cam face 158(Fig. 2) which is formed upon the tripbar to ride over the adjacent edgeof the bracket 156, thus swinging the upper end of the trip-baroutwardly from beneath the tail of the locking pawl and permitting thepawl to return into engagement with its ratchet wheel 134, so as to lockthe conveyer against further forward movement after the feeding pawl 118has ceased to act. As the feed-table descends, the trip-bar 144 is resetso that it is ready to function again at the next operation of thecompressor.

The transferrer 16, by means of which the heels are transferred from theclamps of the heel-press to the conveyer 14, comprises an arm 162 (Figs.3 and 4) which is pivoted for horizontal swinging movement on apost 164rising from the feed table 35 of the heelpress. The arm 162 carries apair of clamp arms 166 between which the heels are gripped. In orderthat the transferrer arm 162 may be swung toward and from the press, a

rearward extension 168 of the arm is connected by means of a. rod 170 toone arm of a cam lever 17 2 (Fig. 5) which is fulcrumed on a stud 174projecting from a portion of the frame of the compressor. The other armof the cam lever 17 2 carries a cam roll 176 which is received in agroove in a cam 17 8 that is secured to the crank shaft 58 of thecompressor. The clamp arms 166 are pivotally mounted on the underside ofthe transferrer arm 162 and at the outer ends of the clamp arms areseverally pivoted clamp plates 180, which are adapted to engage theopposite curved edges of a heel.

In order that the clamp arms 166 may be moved simultaneously toward andfrom each other so as to cause the clamp plates 180 to grip or releasethe heel, the arms 166 are connected by means of intermeshing segmentalgears 182. The inward or clamping movement of the arms 166 is effectedby a spring 184 which extends from one of said arms to the other. Theclamp plates 180 are curved to conform to the curved contour of thelateral edges of the heel and by reason of their pivotal connection withthe clamp arms 166 are permitted to readily adjustthemselves to theheel.

lVhenthetransterrer arm 162, as it swings toward the heel-press,approaches the end of its movement, a. lug 194. on the dog -18d isengaged by a trip-pin 196 depending from a horizontal brackety198 thatis secured to the top of the post 164, the pin causing the dog to swingout from behind-theextension 190 of the clamp :arm andpermitthe spring18% to swing the clamp, arms toward each other, ,thus causingthelclampplates 180 to seize the heel preparatory to, removing it from the openClarhphof-the heel-press. Atthe beginning of operations, before-the-ro-- tary carrier of the heel-press has made a complete revolution,there will be no heelsin'the heel clamps oft-the carrier to beremoved bythe transferrer 16. I the absence, of a heel in the clamp ofthecarrieratthedischarge station 26vwhen the transferrer 16 swingsinwardly, the closing movement of the clamp arms 166 of the transferrerwillbe limited by the engagement of-the extension 190with fa portionofthe lug 19 1.

Afterseizing a heel the trans-ferrer arm 162 is swungaway "fromgthepress, transferring the heel to the position indicated at 200, in: Fig:8, directly aibove an empty link 1 i of the conveyor chain'which'wasadvanced to theposition it occupied in the press, As theclamparms swing outwardly, the clampinto position to receive the heel atgtlhelast feed'movement'ofthe conveyer.

Heel compressors, heretofore employed,

have Ibeen constructed. and arranged to ..op

erate continuously and accordingly the heels were subjected tocompressiononly"whilethe cross-head-of-theucompressor was inumoentarilyin its uppermost'lposition. 3111 the pres- 'ent machine,a certain periodof time ,necessar1ly-elapses between successlve. cycles of operation ofthe compressor, before a f-resh heel has been introduced,into-the .press,and the cam 96 hasroperatedhztosagain start the compressoi and,.l inJorder to {increase the effectiveness of :the compressor the arrangementis such that the operationof thecom- V pressor is arrested when l the crss-head :is n

as heretofore, more smoothly finished and more thoroughly.compressedheels arefproduced.

V The compressor is automatically stopped after each cycle of,openations by cam-actuated mechanisinb which breakslthe toggle 78-80,andpermits the, spring 72 to raise the arm *FOand rock-the shatt tla {ina direction toshiftthe driving belt from the gf ast pulley 54 to theloose pulley 56. In the conperiphery of the cam 178.

struction shown, a bell-crank lever 214 (Fig. 5) is fulcrumed on thestud 174, alongside the lever 172, and carries at the end of its upperarm a cam roll 216 which rides on the periphery of the cam 178. Thelever 214 is actuated by a projecting portion 218 on the The lower armof the lever 214 is connected by a rod 220 with an arm 222 (Fig. 6)which is secured to a rock shaft 224 that is j o-urnaled in bearings onthe frame of the compressor. Extending downwardly from the rock shaft224 is a trip-arm 226 which is adapted to-engage a dog 228 that ispivoted, intermediate its upper and lower extremities, upon an upwardextension of the toggle link 80 and is normally held by a spring 230with its lower end against a shoulder 232 on the extension of the togglelink 80. At each cycle of operations of the machine, after the toggleformed by the members 78 and 80 is straightened, to start the operationof the compressor, the trip-bar 226 first swings in a counterclockwisedirection, viewing Fig. 6, and the dog 228, when engaged by thetrip-arm, rocks idly against the tension of the spring 230, permittingthe trip-arm to pass beyond the dog. The dog 228 is then restored by itsspring 230 to its normal position against the shoulder 232. Upon themovement of the trip-arm in the opposite direction, however, just beforethe compressor is automatically brought to rest, the dog 228 isprevented from rocking about its pivot by the shoulder 232 and as aresult the toggle link 80 is swung by the trip-arm in a direction tobreak the toggle 78-80 and cause the shaft 68 to be rocked so as toeffect the shifting of the belt from the fast pulley of the compressorto the loose pulley. The compressor is then brought to rest with thecompressing instrumentalities closed to hold a heel un* der compression.

The operation of the machine is as follows: Assuming that the heel-pressand the conveyer 14 are filled to capacity with rough heels, theoperator places a previously pasted rough heel between the gage members36 of the feed-arm 34 and depresses the heel slightly to operate thetrip-plate 38. The feed-arm then swings inwardly toward the heel-press,introduces the heel into an empty heel clamp which is open and ready toreceive it at the receiving and discharging station 26, and immediatelyreturns to its normal retracted position. The inward movement of thefeed-arm automatically starts the operation of the press, rotating theclamp carrier 20 one step, in the direction of the arrow in Fig. 1,thereby advancr ing the next heel clamp into position to discharge itsheel and receive a new heel. The step movement of the clamp carrieroperates in the manner hereinbefore described to start the operation ofthe compressor which is normally at rest with the cross-head in itsuppermost position holding a heel under pressure in the mold. As thecompressor starts to operate, the cross-head 44 and feedtable 46descend, and at the same time the feed-slide 50 advances toward the heelmold in the cross-head, carrying a rough heel which was depositedthereon at the preceding cycle of operations. The transferrer 18, whichwas ositioned with its clamping jaws 208 extending over the feed-slide50, swings toward the conveyer and the jaws 208 close upon the. heelthat is carried at the leading end of the conveyer. At the end of thedownward movement of the cross-head 44 the heel, which was compressed atthe preceeding cycle of operations of the compressor, is ejected by thefeed-slide from the mold and the rough heel carried by the feedslide indeposited in the mold. The crosshead and feed-table then rise, thefeed-slide being simultaneously retracted from the mold. On the upwardmovement of the cross-head and the feed-table the transferrer 18 startsto swing toward the feed-table. The conveyer is then unlocked andadvanced through the space of one link, bringing another heel intoposition to be seized, at the next cycle of operations, by the clampingjaws of the transferrer 18, and advancing an empty link into position toreceive a heel from the press before the completion of the presentcycle. As the cross-head reaches its uppermost position, it comes intocooperative relation with the heel-seat die compressing the heel in themold. The feedslide is then in its fully retracted position and the heelcarried by the transferrer 18 is deposited thereon. During the last partof the cycle of operations of the compressor and just afterthe advanceof the conveyer chain, the transferrer 16 is swung toward the press andseizes the heel, which is in the open clamp at the station 26, andimmediately returns and deposits the heel upon the empty link of theconveyer chain. The triparm 226 is then actuated to break the toggle,comprising the members 78 and 80, and the compressor is automaticallystopped with the cross-head in its uppermost position, holding a heelunder compression in the mold. The operator then places anotherpreviously pasted rough heel between the gage members of the feed-arm 34and depresses the heel, thus causing the feed-arm to swing inwardly, asbefore, introducing another heel into the press and initiating anothercycle of operations of the machine. From the foregoing description itwill be apparent that while the pressing and the compressing mechanismsof the present machine are independently driven and loosely connectedwith a source of power, by means of driving belts which are liable toslip and normally closed, means for initiating the pietion of eachsuccessive-cycle of operations, With the compressinginstrumentalitiesol0secl"11pon the heel, insures the pro- "duction' ofheels which are-more smoothly finished and more thoroughly compressedthal'i'tho'se produced by compressing mechani ms hereto-fore employed.
